LTC2911IDDB-2

Supervisors Overview

The LTC2911IDDB-2#TRMPBF is a precision triple supply monitor manufactured by Analog Devices Inc. in an 8-lead DFN package. It features three voltage monitoring channels: V1 monitors a fixed 3.0V supply, V2 monitors a 1.2V or adjustable supply, and V3 provides a nominal 0.5V threshold for configurable inputs via resistive dividers. The device includes a power-fail comparator with selectable hysteresis and a push-pull reset output. It operates within a temperature range of -40°C to 85°C and consumes low quiescent current.

Supervisors Feature Summary

• Monitors three distinct voltage inputs simultaneously with high accuracy
• Integrates a power-fail comparator with selectable hysteresis
• Provides a push-pull reset output with selectable timeout
• Supports configurable thresholds on the third input channel

Supervisors Applications

• Multi-rail power system supervision
• Portable equipment power management
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the specific suffix (#TRMPBF) indicates tape and reel packaging when ordering. Confirm the DFN-8 package variant matches your PCB footprint requirements. Ensure the component meets RoHS compliance standards for your manufacturing process. Check availability status as supply levels may vary by region. Validate that the operating temperature range suits your environmental conditions.

Supervisors Selection Notes

Select this part when simultaneous monitoring of three voltage rails is required. Choose the IDDB-2 variant specifically for its fixed 3.0V and 1.2V monitoring capabilities combined with an adjustable third channel. Consider the push-pull output if driving loads directly without additional buffering. Evaluate the low quiescent current for battery-operated applications requiring extended standby life.

Supervisors Part Context

The LTC2911 series consists of low-power, high-accuracy triple supply monitors designed for advanced power management. The IDDB-2 variant specifically targets applications needing fixed monitoring at 3.0V and 1.2V alongside a flexible third channel. This family integrates power-fail detection and reset generation into a compact surface-mount package.
